I will give you a similar example, OK? http://openstudy.com/study#/updates/52697f82e4b040e33d2f88e7

anonymous · Answer

Okay give me a moment to look over the example. : )

solomonzelman · Answer

that one is about perpendicular line not parallel, do you want to do this one together?

solomonzelman · Answer

1) put    ' 2x + 3y = 5 '  inot a standard from  (y=mx+b)

solomonzelman · Answer

into, not inot

anonymous · Answer

Umm.. ' 3y= -2x+5 '

solomonzelman · Answer

OK, now divide all sides by 3, to set it equal to y

anonymous · Answer

' y = -2/3x + 5/3 '

solomonzelman · Answer

yep!

solomonzelman · Answer

now what point does your parallel line pass through? plug in this point into the above equation ' y = -2/3x + 5/3 ' 

the slope is the same, don't touch it, b/c the lines are parallel.

solomonzelman · Answer

I mean y = -2/3x + b  plug in your coordinate to find b

anonymous · Answer

So I plug -3 into b? because -3 is the point in which it crosses the y-axis? Or am I all confused o~o I kinda suck at understanding this stuff.. Sorry

solomonzelman · Answer

no plug in  ' (9, -3)'  into y = -2/3x + b  to find the b.

anonymous · Answer

I don't know where to plug it in at ;-;

solomonzelman · Answer

what is the x coordinate in (9, -3)? and what is the y coordinate in (9, -3)?

anonymous · Answer

9=x -3=y

solomonzelman · Answer

plug that into y = -2/3x + b

solomonzelman · Answer

plug 9 for x, and -3 for y into y = -2/3x + b

anonymous · Answer

I was showing my friend.. Just about to say I get it now.. lol I'm slow sometimes.. 
-3 = -2/3(9) + b

solomonzelman · Answer

so what is the b?
